Tewksbury is horse country in the northeast corner of Hunterdon, built around the village of Oldwick and the hamlets of Mountainville and Pottersville, with wooded ridges and large properties along Route 517 and Route 523. The building stock ranges from centuries-old village houses to large custom homes and converted barns, and many of them have outbuildings with their own heat and water. We plan work around what is actually on the property rather than a standard house.
Heights Plumbing, Heating & Cooling is a family-owned, licensed and insured plumbing and HVAC company serving the township of Tewksbury in Hunterdon County, New Jersey. We offer same-day service, on-time arrival and upfront No Worries Pricing on every job, and we handle residential and commercial work.
What We See in Tewksbury Homes & Buildings
- Guest houses, barns and detached studios frequently have their own heating, plumbing and fixtures, and they need to be inspected and maintained alongside the main house.
- Old village houses in Oldwick and Mountainville commonly heat with hot water or steam radiators, where the right first move is servicing controls, venting and circulation before condemning the boiler.
- Large custom homes here are hard to condition evenly, and adding zoning or a ductless head for a converted attic or wing is usually cheaper than oversizing the whole system.
Sections of Tewksbury we serve include Oldwick, Mountainville, Pottersville, along with every other part of the township.

Tewksbury Plumbing & HVAC FAQs
Can you service a barn or guest house that has its own heat and plumbing?
Yes. Outbuildings are common on Tewksbury properties and we treat them as part of the job, including the water line feeding them and the risk of freeze damage in a space that is not heated year round.
Our radiators are old but the house is warm. Should we replace the boiler?
Not automatically. A well-maintained boiler with sound radiators can keep going for a long time, and we would rather service the controls, circulators and venting than sell you equipment you do not need yet.
The upstairs of our house never cools down in summer. Why?
In a large or added-onto house it is almost always distribution — heat gain upstairs outruns what the ducts can deliver. Zoning, duct corrections or a ductless head for the problem area usually solves it without replacing the whole system.
